i want to all physical ,chemical ,and machanical properties of pant with calculation………..plz. Thanks sir. Paints can be defined as: “A liquid solution of pigment ( coloring material ) and solvent, which is applied on different surfaces for decorative or protective reasons.”, It can also be defined as: ” Dispersion of pigment ( coloring substance ) in a suitable drying oil in the presence of a solvent ( paint thinner ) is known as paint.”. It consists of a very fine powder of a suitable material such as white lead, red lead, iron oxide, and titanium oxide, etc. Zinc oxide is a weaker white pigment with some important usages. So, now I think the term “what is paint” will be cleared. Generally speaking, paint has 3 components: pigment, binder and solvent. In Red Color: Red Lead, Venetian Red, Chrome Red, Natural Red Oxides of Iron are used as a pigment. Pigments are simply the color chemical (typically a metal compound) in paint and is typically a solid. Separate, identify, and quantify the organic components of a coating or paint Detect impurities in an organic coating material to ppb concentrations. Costly paints should not be used in common constructions. Two basic categories of chemical paint removers are caustic and solvent. Besides the three main categories of ingredients, paint can have a wide variety of miscellaneous additives,usually added in very small amounts. Pigment is added in a finely powdered state. Gotthard Base Tunnel (Rail Tunnel) Design Engineering, Construction & Cost, Structural & Non Structural Defects in Building Construction, SAP 2000 and ETABS Training Course on Realworld Civil Engineering Projects, Make the paint film harder and more resistant to abrasion, Oily liquid in which the body and pigment are soluble, Facilitates the paint to be conveniently spread over the surface, Organic salts of Iron, zinc, lead, manganese, Ca, To accelerate the oxidation and hardening of vehicle. The backbone composition is the foundation of the manufacturer's brand style and quality standards. In white paint the body is the pigment. It imparts adhesion, binds the pigments together, and strongly influences such properties as gloss potential, exterior durability, flexibility, and toughness. Chemicals are mainly used on site and infra-red is used in the lab. It is most commonly used to protect, color or add texture to objects. Pigments, usually insoluble powders, are used both to provide color, and to make paint opaque, thus protecting the substrate from the harmful effects of ultraviolet light while also increasing a paint's hiding power. I know that now you will ask about Paint Definition, don’t be worry. Common thinner ► turpentine (made by distilling gum from a number of pine trees). However, basically all paints consist of the following five components. Good day sir. In Yellow Color: Chrome Yellow, Zinc Chromate, Yellow Ochres are used as a pigment. What is Plastering. Commonly used extenders are: Chalk, gypsum, barite, silica and magnesium silicate. The Ingredients in Paint. Solvent based, sometimes called oil based, paints can have various combinations of solvents as the vehicle, including aliphatics, aromatics, alcohols, and ketones. The variety of paint products offered can be overwhelming. It usually includes most or all of the following ingredients: • one or more pigments, and sometimes • a brightener, transparent or "white" crystals that lighten the value and increase the chroma of the dried paint. | Define Plaster, Cement Plasters & Gypsum Plaster. Basic Components of Paints Paint is a very complex material consisting of many components. Oil paint on the other hand, may not fully dry for weeks: you can play with it, correct its tones and even erase missteps from the canvas and start again on a section. Some examples include additives to improve wet edge, to impart antifreeze properties, control foaming, control skinning, fight bacterial growth, or improve pigment stability. Kaoline Clayis a natural colloidcontaining finely dispersed particles of hydrated aluminum silicate. Although its primary purpose is to protect the surface to which it is applied, paint also provides decoration.
